Facts and Figures from NHDES

* Over 55 of New Hampshire's waterbodies are impacted by various species of EXOTIC aquatic plants.
* The dispersal of plant fragments poses the greatest threat to our waterbodies. Each fragment is capable of producing another plant.
* EXOTIC aquatic plants can reduce the diversity of native plant, animal, and insect species.
* Most NATIVE plant species are very beneficial to our waterbodies, providing food, shelter, and oxygen for organisms in and around the water.
* EXOTIC aquatic plants can reduce the value of waterfront properties.
* EXOTIC aquatic plants can make boating and swimming difficult and dangerous.
* Dense growths of EXOTIC aquatic plants can stunt fish growth, impacting the fisheries in our waterbodies.
* Milfoil and fanwort can grow as tall as 20 feet in waterbodies they infest.
* Of the fourteen species of prohibited exotic plants, eight are currently found in New Hampshire. Others are already present in neighboring states!
* YOU can help prevent the spread of exotic aquatic plants.
